qiime cutadapt trim-paired --help

Usage: qiime cutadapt trim-paired [OPTIONS]Search demultiplexed paired-end sequences for adapters and remove them. 搜索并删除双末端序列中得接头序列 The parameter descriptions in this method are adapted from the official cutadapt docs - please see those docs at https://cutadapt.readthedocs.io for complete details.Inputs: --i-demultiplexed-sequences ARTIFACT SampleData[PairedEndSequencesWithQuality] The paired-end sequences to be trimmed.[required] Parameters: --p-cores INTEGERNumber of CPU cores to use. Range(1, None)[default: 1] --p-adapter-f TEXT...Sequence of an adapter ligated to the 3' end. The List[Str]adapter and any subsequent bases are trimmed. If a `$` is appended, the adapter is only found if it is at the end of the read. Search in forward read. If your sequence of interest is "framed" by a 5' and a 3' adapter, use this parameter to define a "linked" primer - see https://cutadapt.readthedocs.io for complete details.[optional] 连接到3’端得接头,裁剪接头序列和其后任意碱基。如果附加了' $ ',则只有在read的末尾才会检索接头。向前检索。 --p-front-f TEXT...Sequence of an adapter ligated to the 5' end. The List[Str]adapter and any preceding bases are trimmed. Partial matches at the 5' end are allowed. If a `^` character is prepended, the adapter is only found if it is at the beginning of the read. Search in forward read.[optional] 连接到5'端接头的序列。裁剪接头和前面任意碱基。允许5'端部分匹配。如果添加了' ^ '字符,则只有在read开始时才检索接头。 --p-anywhere-f TEXT...Sequence of an adapter that may be ligated to the List[Str]5' or 3' end. Both types of matches as described under `adapter` and `front` are allowed. If the first base of the read is part of the match, the behavior is as with `front`, otherwise as with `adapter`. This option is mostly for rescuing failed library preparations - do not use if you know which end your adapter was ligated to. Search in forward read.[optional] --p-adapter-r TEXT...Sequence of an adapter ligated to the 3' end. The List[Str]adapter and any subsequent bases are trimmed. If a `$` is appended, the adapter is only found if it is at the end of the read. Search in reverse read. If your sequence of interest is "framed" by a 5' and a 3' adapter, use this parameter to define a "linked" primer - see https://cutadapt.readthedocs.io for complete details.[optional] --p-front-r TEXT...Sequence of an adapter ligated to the 5' end. The List[Str]adapter and any preceding bases are trimmed. Partial matches at the 5' end are allowed. If a `^` character is prepended, the adapter is only found if it is at the beginning of the read. Search in reverse read.[optional] --p-anywhere-r TEXT...Sequence of an adapter that may be ligated to the List[Str]5' or 3' end. Both types of matches as described under `adapter` and `front` are allowed. If the first base of the read is part of the match, the behavior is as with `front`, otherwise as with `adapter`. This option is mostly for rescuing failed library preparations - do not use if you know which end your adapter was ligated to. Search in reverse read.[optional] --p-error-rate PROPORTION Range(0, 1, inclusive_end=True) Maximum allowed error rate.[default: 0.1] --p-indels / --p-no-indels Allow insertions or deletions of bases when matching adapters.[default: True] --p-times INTEGERRemove multiple occurrences of an adapter if it is Range(1, None)repeated, up to `times` times.[default: 1] --p-overlap INTEGERRequire at least `overlap` bases of overlap between Range(1, None)read and adapter for an adapter to be found. [default: 3] --p-match-read-wildcards / --p-no-match-read-wildcards Interpret IUPAC wildcards (e.g., N) in reads. [default: False] --p-match-adapter-wildcards / --p-no-match-adapter-wildcards Interpret IUPAC wildcards (e.g., N) in adapters. [default: True] --p-minimum-length INTEGER Range(1, None)Discard reads shorter than specified value. Note, the cutadapt default of 0 has been overridden, because that value produces empty sequence records. [default: 1] --p-discard-untrimmed / --p-no-discard-untrimmed Discard reads in which no adapter was found. [default: False] Outputs: --o-trimmed-sequences ARTIFACT SampleData[PairedEndSequencesWithQuality] The resulting trimmed sequences.[required] Miscellaneous: --output-dir PATHOutput unspecified results to a directory --verbose / --quietDisplay verbose output to stdout and/or stderr during execution of this action. Or silence output if execution is successful (silence is golden). --examplesShow usage examples and exit. --citationsShow citations and exit. --helpShow this message and exit.
